The basic problem of this investigation concerns how is it that an individual "understands" or "comprehends" what another communicates and, sometimes, even what he does not communicate but of which he has experience. We would like here to take stock of the models that psychology currently has available to study the phenomenon of interpersonal understanding,using a cognitive approach, and to propose some working hypotheses that in our opinion could guide further research.

The problem discussed in this paper arises from the observation that in the course of inter-subjective communication "understanding" seems to be entrusted to the implementation of a real process, not only affective but also cognitive, of processing information contained in the perceived behavior. In a previous study (Greco, 1979) we proposed to consider this process of "reconstruction" of meaning as analogous to the process of "construction" used for oneself. Here we will deal with this process of construction or awareness using (...) theoretical models offered by experimental research. (shrink)

Starting from some remarks about the use of models in psychology, Human Information Processing (henceforth called H.I.P.) models which sometimes use computer simulation will be examined. An attempt to show that simulation in psychology does not necessarily imply an H.I.P. approach is then made.
